Magnetism fosters unusual electronic order in quantum material

Posted by in categories: energy, quantum physics

Physicists were surprised by the 2022 discovery that electrons in magnetic iron-germanium crystals could spontaneously and collectively organize their charges into a pattern featuring a standing wave. Magnetism also arises from the collective self-organization of electron spins into ordered patterns, and those patterns rarely coexist with the patterns that produce the standing wave of electrons physicists call a charge density wave.

In a study published this week in Nature Physics, Rice University physicists Ming Yi and Pengcheng Dai, and many of their collaborators from the 2022 study, present an array of experimental evidence that shows their charge density wave discovery was rarer still, a case where the magnetic and electronic orders don’t simply coexist but are directly linked.

“We found magnetism subtly modifies the landscape of electron energy states in the material in a way that both promotes and prepares for the formation of the charge density wave,” said Yi, a co-corresponding author of the study.

Enzymes could make it cheaper to recycle waste polyester textiles and bottles than making them from petroleum

Posted by in categories: energy, sustainability

What do a T-shirt, a rug, and a soda bottle have in common? Many are made from polyethylene terephthalate (PET), a ubiquitous plastic that revolutionized the materials industry after it was patented in the 1940s.

Created from petroleum refining, PET is a material known for its durability and versatility. It is easily molded into airtight containers, woven into durable carpets, or spun into polyester clothing.

“The reality is that most PET products—especially PET clothing and carpeting—are not recycled today using conventional technologies,” explained Gregg Beckham, senior research fellow at the National Renewable Energy Laboratory (NREL) and CEO of the U.S. Department of Energy BOTTLE Consortium. “The is developing promising alternatives, including enzymes designed to depolymerize PET, but even these options have tended to lean on energy-intensive and costly preprocessing steps to be effective.”

In defense of space colonies and mining the high frontier

Posted by in categories: energy, finance, internet, satellites, sustainability

Exploiting the natural and energy resources of the moon and asteroids can spark a space-based industrial revolution that could be a boon to all humankind. Pure science alone will be enough reason for the people who pay the bills to finance space exploration. Accessing the wealth that exists beyond the Earth is more than enough incentive for both public and private investment. Science will benefit. Someone will have to prospect for natural and energy resources in space and to develop safe and sustainable ways to exploit it.

Conflict between scientists and commercial space is already happening. Astronomers complain that SpaceX’s Starlink satellite internet constellation is ruining ground-based observation. Some critics fear that commercial exploitation of the moon’s resources will impede the operation of telescopes on the far side of the moon.

Fossil Fuel Industry Leadership Intends To Stay As “Oily” As Possible Until Forced To Change

Posted by in categories: energy, futurism

Oil company CEOs greenwash at Houston conference while UN calls for action to halve emissions from the industry this decade.


The fossil fuel industry sees a ‘chaotic’ and ‘painful’ future in curbing their production before proven energy alternatives are in place.

A super-resolution microscopy method for rapid differentiation of molecular structures in 3D

Posted by in categories: chemistry, energy

Super-resolution microscopy methods are essential for uncovering the structures of cells and the dynamics of molecules. Since researchers overcame the resolution limit of around 250 nanometers (while winning the 2014 Nobel Prize in Chemistry for their efforts), which had long been considered absolute, the methods of microscopy have progressed rapidly.

Now a team led by LMU chemist Prof. Philip Tinnefeld has made a further advance through the combination of various methods, achieving the highest resolution in three-dimensional space and paving the way for a fundamentally new approach for faster imaging of dense molecular structures. The new method permits axial resolution of under 0.3 nanometers.

The researchers combined the so-called pMINFLUX method developed by Tinnefeld’s team with an approach that utilizes special properties of graphene as an energy acceptor. pMINFLUX is based on the measurement of the fluorescence intensity of molecules excited by laser pulses. The method makes it possible to distinguish their lateral distances with a resolution of just 1 nanometer.

Scientists Discover Enzyme That Can Turn Air Into Electricity

Posted by in categories: energy, sustainability, transportation

In an exciting turn for the field of sustainable energy research, Australian scientists have found a way to make energy out of thin air. Literally.

As detailed in a new study published this week in the journal Nature, researchers from Monash University in Melbourne, Australia discovered a new bacterial enzyme that transforms the traces of hydrogen in our atmosphere into electricity, technology that could one day be used in fuel cells that power anything from a smartwatch to even a car.

“We’ve known for some time that bacteria can use the trace hydrogen in the air as a source of energy to help them grow and survive, including in Antarctic soils, volcanic craters, and the deep ocean,” said Professor Chris Greening, a contributor to the study, in a statement.

This 1,000-foot Multi-Rotor Floating Turbine Can Power 80,000 Homes

Posted by in categories: energy, sustainability

A Norwegian Greentech company has recently unveiled its new 1,000-foot (324m) tall, floating wind turbine array. Called “Wind Catcher”, this innovation in renewable energy generation could be used to power as many as 80,000 homes.

The system has been developed by the Norwegian-based Wind Catching Systems (WCS), who declare that their new wind turbine setup could generate five times the annual energy of the world’s biggest standalone wind turbines. Not only that, but if scaled, it could reduce the costs of wind energy to be competitive with traditional grid-supplied electricity.

New Superconducting Material Could Transform Electronics — If It Works

Posted by in categories: energy, materials

Superconductivity is an incredible property of certain materials with exciting consequences. Once reached, for example, said materials can conduct electricity without resistance, so no loss of energy. But most materials are superconductive at extremely low temperatures. The quest for a room-temperature superconductor is ongoing, and is not without a bit of scientific drama.

A few years ago, there was a claim of a room-temperature superconductor that became supercritical at a temperature of 15°C (59°F), but required a pressure of 2.5 million atmospheres. That’s on the order of the pressure you might find in the core of a rocky planet, and can be achieved by squeezing materials between two diamonds. Other scientists raised issues with the way the numbers were handled, including an accusation of the data used being fabricated.

The paper was retracted by the journal Nature last September, and the team claims they are ready to resubmit that work. They have also announced a brand-new material with even more extraordinary properties (if confirmed). The new substance is described as a nitrogen-doped lutetium hydride that becomes superconductive up to 20.5°C (69°F) and at a much lower pressure, roughly 10,000 atmospheres. Quite the improvement.
